Frequently Asked Questions1. Won't my house be too tight?Yes, most houses constructed today are too tight no matter what the insulation. You should always add a fresh air system to your home to pre filter your air to remove any contaminates such as dust, pollen, mold and any other airborn allergines. Remember build it tight and ventilate right. You can not depend on mother nature or poor craftmanship to supply you with fresh air. 2. Doesn't Spray Foam Insulation cost more that fiberglass insulation?Yes it does cost more but is still an affordable up front cost. With 70% of the energy lost in a home is due to air infiltration - PLUS - factoring the savings gained from HVAC load requirements, monthly reduction in utility costs, air quality gains, mold protection, R-value gain, structural impact, rebates, and the GONE GREEN from PINK-the rewards exceed financial. 3. Is there really a big difference in fiberglass insulation and Spray Foam Insultation?(Source: SprayFoam.org with a R&D Services at Oak Ridge National Laboratories) Three attic insulation systems were tested in the LSCS for both Winter and Summer conditions. The thermal test section has dimensions 8x8 ft. and area of 64 ft.
Results:The tests results demonstrate that both low density and medium (2 lb) density SPF installed to the underside of the roof deck in attic assemblies maintain a much higher effective R-value at both low and high temperatures than the fiberglass insulation system. The SPF systems maintained 74% and 83% respectively of reported R-value at low outside temperatures compared to 46% for the fiberglass assembly, and 61% and 67% of reported R-value at high outside temperature compared to 51% for the fiberglass assembly. Attic temperatures of low density and medium density SPF assemblies averaged 77 to 78 degrees F at high outside temperature and 60 – 61 degrees F at low outside temperature compared to an average of 107 degrees at high outside temperature and 7 degrees at low outside temperature for the fiberglass assembly. |
